REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No. 14/377,563, filed Aug. 8, 2014, which is a national phase application of, claims priority from, and incorporates by reference the disclosure of PCT Application No. PCT/US2014/044690, filed Jun. 27, 2014, which claims priority to U.S. Provisional Application No. 61/840,321, filed on Jun. 27, 2013, and is also incorporated by reference herein.

BACKGROUND

A typical bead snipper may include a cutting member that is coupled to a press button and is housed in a chamber that has an opening for accepting therethrough a stem and is horizontally aligned to a groove that is directionally perpendicular to the opening and within which the cutting member is pressed in while cutting the stem. During operation, the user does not have a visible idea of a length of a generated bead and has to keep pushing the stem into the chamber after each cut in order to generating additional beads.

A conventional bead snipper includes a housing that has on one back end an opening for sliding a stem into a chamber of the housing, a push lever positioned on the top of the housing for cutting when pressed the stem into beads. The conventional stem snipper further includes a sliding button positioned one side of the housing for controlling a length of the beads to be produced through a cutting process of the stem. However, during the cutting process of a stem, the user does not have a visible idea of a length of a generated bead, and the bead snipper also requires that the user keeps pushing the stem into the housing to generate additional beads.

Accordingly, there is a need for, among other things, a bead snipping device that gives the user a mechanism advantage making it easier for the user to cut the stems and tubes.

The examples used herein are intended merely to facilitate an understanding of ways in which the present disclosure may be practiced and to further enable those of ordinary skills in the art to practice the embodiments of the present disclosure. Accordingly, the examples and embodiments herein should not be construed as limiting the scope of the present disclosure, which is defined solely by the appended claims and applicable law. Moreover, it is noted that like reference numerals represent similar parts throughout the several views of the drawings.

As stated above, typical bead snipping device/apparatus require that a user persistently pushes a bead stem towards a cutting feature/element of the device in order to keep generating beads via cutting operations.

Accordingly, the present disclosure provides a device used for the purpose of cutting stems, such as Perl stems, to produce Perl beads, and gives the user a mechanical advantage making easier for the user to cut the stems and tubes while providing the user a measurement feature to generate desirable sized beads, and may not require that the user keeps handling manually the stem during the bead generating process.

Now referring to FIGS. 1 and 2, an exemplary embodiment of a snipping device 100 used for cutting or snipping bead materials, such as a bead material used in crafting, is shown. The bead material may be beads, stems, rods, and the like. For example, the bead material may be Perler Beads® or stems used in crafting.

As shown in FIGS. 1 and 2, snipping device 100 includes a base 102, a cutting chamber 104, and an actuation member (e.g., a cutting or press arm) 106. Base 102 may include a top surface 108 in which a stem material guide 110, such as a groove, a channel, or a bore, is routed. Alternatively, stem material guide may be a tube formed on top surface 108. Stem material guide 110 is formed to maintain, position, and guide the stem material that is desired to be cut into segments or pieces, such as beads. As shown, stem material guide 110 is rounded on the bottom 110 a and at both open ends, i.e., loading end (not shown) and dispensing end 110 b. In one embodiment, base 102 may include protrusions extended vertically above top surface 108 and lengthwise along stem material guide 110 to prevent stems from sliding out of stem material guide 110.

In one embodiment, the loading end of stem material guide 110 may be topped by a down facing groove 112 formed at a bottom end of cutting chamber 104 to form a cylindrical channel 114 for the stem. As such, at the loading end of stem material guide 110, cylindrical channel 114 provides a loading opening through which the bead material stem can be loaded into snipping device 100.

As shown in FIGS. 1 and 2, base 102 further includes measurement markings 110 c located adjacently lengthwise to stem material guide 110 to enable the user to accurately cut the stems into different sized beads. As such, measuring stops of the stems enables the user to consistently cut the bead material stem into desired sizes.

In one embodiment, base 102 may be sized and shaped to be aesthetically pleasing and to be and remain in a stable position on a supporting surface during the stem cutting operations. For example, base 102 may rest freely on a horizontal surface of a table or a desk or be attached to an angled surface of a wall. Base 102 may include gaskets, feet, or a bottom layer to provide shock absorbance during cutting operations.

As shown in FIG. 2, base 102 is configured to manually advance bead material stem 202 by grasping a back end 202 a of bead material stem 202 and pushing forward bead material stem 202 after each cut so that a front end of a remaining uncut portion of bead material stem 202 is lined up next to a desirable length indicator of measurement markings 110 c.

In one embodiment, base 102 may include an advancing member (not shown) that enables the user to advance or push forward bead material stem 202 indirectly by pushing the advancing member.

In accordance with the present disclosure, cutting chamber 104 includes integrally a stem advancement mechanism (not shown) that is configured to automatically move bead material stem 202 after cutting operations.

In one embodiment, cutting chamber 104 includes therein a cutting member (not shown), such as a razor, a knife or the like, used to cut or snip bead material stem 202 within stem material guide 110, which is coupled to cutting arm 106 to handle the cutting or snipping process. Moreover, cutting member may be cooperatively engaged with a biasing member (not shown) that operates to return the cutting member to a desired position above stem material guide 110, and to raise angularly cutting arm 106 to a corresponding angle. Alternatively, biasing member may be directly engaged with cutting arm 106 and indirectly to the cutting member via cutting arm 106. The biasing member may include a leaf spring, a compression spring, a torsion spring, and the like.

The cutting member may be positioned in cutting chamber 104 in a perpendicular direction to that of stem material guide 110, which includes an opening within which the cutting member enters so that bead material stem 202 is cut on a vertical circumferential axis when cutting arm 106 is pressed downwards by the user. Alternatively, the cutting member may be positioned in an angular non-perpendicular direction in relation to stem material guide 110 to cut or snip stem material guide 110 in a non-perpendicular manner. In one embodiment, the cutting member may include a housing that receives a razor blade that can be removed or replaced.

As stated above, snipping device 100 includes as an actuation member 106 that is shaped a cutting/press arm. Alternatively, actuation member 106, hereafter referred to as press arm, may be a button, a lever, and the like. Moreover, as discussed above with regard to press arm 106, the actuation member may be cooperatively engaged with the biasing member so that a release of the actuation member by the user causes the cutting member to return to an open or ready to cut position. In lieu of being coupled to one another, the actuation member and the cutting member may be connected as an integral mechanism, which in turn is connected to the biasing member. For example, the actuation member may be a push button that is directly connected to the cutting member that includes a sharpened metal plate. As such, during a cutting operation, when the user presses downwards on the push button the cutting member is moved downwards through bead material stem 202.

In one embodiment, when the biasing member is directly engaged to the actuation member, then after bead material stem 202 is cut and the user has stopped pressing the actuation member, the biasing member forces back up the actuation member and the cutting member.

As shown in FIGS. 1 and 2, press arm 106 may be configured to be aesthetically and/or ergonomically pleasing. Press arm 106 may be formed from comfortable material, sized and shaped to provide a large contact surface for the user to press on, and may also an additional biasing member to assist in the cutting motions.

Press arm 106 may be oriented on snipping device 100 in a desirable direction that provides a desirable movement direction during the cutting operations. In one embodiment, press arm 106 may face the user and require the user to press down to cut bead material stem 202. Alternatively, press arm 106 may face away from the user or be turned sideways with respect to the user, thereby allowing for other cutting motions such as pushing away or pulling towards the user.

As stated above, in one embodiment cutting chamber 104 may include a stem advancement mechanism that is configured to automatically move bead material stem 202 after each cutting operation, thereby removing a requirement that the user manually pushes bead material stem 202 after each cutting operation to generate additional beads. In one exemplary embodiment, the stem advancement mechanism may be adjustable by the user to enable advancement of bead material stem 202 at different lengths thereby enabling a production of beads with desirable lengths during a process of cutting bead material stem 202. Alternatively, the stem advancement mechanism may be configured to advance bead material stem 202 based on how high press arm 106 is allowed to be biasingly raised after the user stopped pressing it. As such, the user can select a length of advancement of bead material stem 202 by choosing a corresponding biased height of press arm 106.

During operation, the user holds bead material stem 202 to insert it into and push it through a back opening of cutting chamber 104 to bring a front end of bead material stem 202 to a desired position on stem material guide 110 wherein measurement markings 110 c indicates a length of the bead to be produced by cutting bead material stem 202. That is, the user uses measurement markings 110 c to aide in the selection of sizes for the desired beads. The user then engages press arm 104 by applying force in a required direction, thereby causing the cutting member to move in a direction to penetrate stem material guide 110 to cut there within bead material stem 202, and snipping the desired bead 204 off bead material stem 202. The user then releases his/her pushing pressure on press arm 106 to which biasing member forces press arm 106 back to the open or ready to cut position. The user then advances the bead material stem 202 within stem material guide 110 to a desired position to repeat the cutting process. Alternatively, bead material stem 202 is automatically advanced within stem material guide 110 by the stem advancement mechanism by a length preselected by the user.

As shown in FIGS. 3 and 4, to render snipping device 100 more stable during cutting operations, base 102 may include suction cup machine feet 302 and 402. Moreover, in lieu of positioning cutting chamber 104 near a back end of base 102, as shown in FIG. 3, cutting chamber 104 may be away from the back end to provide additional support to a portion of bead material stem 202 that has not yet penetrated cutting chamber 104. As shown in FIG. 3, stem material guide 110 is lengthy enough after cutting chamber 104 to maintain therein a certain number of cut pieces, i.e., generated beads, of bead material stem 202. In another embodiment, base 102 may include a hollow portion (not shown) that is positioned a certain distance from cutting chamber 104 and that is wider than stem material guide 110 to collect there within generated beads of bead material stem 202.
